Overview
Run as a Stand-Alone Vision System
National Instruments Vision Builder for Automated Inspection
(Vision Builder AI) is configurable software for building, benchmarking,
and deploying machine vision applications. NI Vision Builder AI does not
require programming. A built-in deployment interface is included so you
can quickly deploy your inspection, guidance, and identification
applications. Also it includes the ability to set up complex pass/fail
decisions to control digital I/O devices and communicate with serial
or Ethernet devices such as PLCs, PACs, and HMIs.
Vision Builder AI includes a built-in deployment interface with which you
can quickly deploy your application once you have finished configuring
and benchmarking.
Integrate into a Larger Application
Use the Vision Builder AI ActiveX component to embed Vision Builder AI
inspections into your NI TestStand, LabVIEW, or Visual Basic programs.
Use the ActiveX control to develop an operator interface that (remotely)
views images and retrieves the results of each run.
Image Acquisition
Choose from several different hardware options within Vision Builder AI
for deploying your machine vision application. Whether you prefer low-cost
analog cameras; high-speed, high-resolution digital cameras; or easy-to-use
IEEE 1394 and GigE Vision cameras; NI has an image acquisition device
for your needs. In addition, you can deploy your machine vision system
using PCI or PCI Express boards, or upgrade to more rugged PXI and
Compact Vision System options.
Machine Vision Tools
A Better Way to Configure Vision Systems
For inspections that require conditional branches or iterative loops,
Vision Builder AI provides an innovative state-diagram-process model.
In this model, you configure each state to perform a certain action, from
acquiring images to reading text to communicating with PLCs. The results of
these steps determine which transition path is taken to the next state.
By using state diagrams, you can create seemingly complex machine vision
applications that provide the flexibility of a programming language with
the ease of use of a configuration environment. Not only are state
diagrams an intuitive way to represent machine vision applications, but
also they are self-documenting and easy to share among colleagues.
Vision Builder AI includes all the machine vision tools necessary
to build quality control, assembly verification, and industrial inspection
applications. Use Vision Builder AI to enhance images, locate features,
measure objects, check for presence, and read text and bar codes.
Advanced Decision Making
With the decision-making interface, you can define pass/fail criteria and
classify parts. You can set limits for each inspection step and also use
the intuitive decision-making interface to create complex decision
expressions for the entire system. You can route the results of these
decisions to digital lines, the user interface, or a serial port.

Vision Software Capabilities
Gauging
National Instruments vision software includes hundreds of image
processing and analysis functions. A subset of the tools available in the
Vision Development Module and Vision Builder AI are shown below.
You can use dimensional measurement or gauging
tools to obtain quantifiable, critical distance
measurements – such as distances, angles, areas,
line fits, circular fits, and counts.
Pattern and Geometric Matching
Bar Code Reader and Grader
Learn and locate objects and patterns in your images.
National Instruments patented matching algorithms
locate patterns fast with very high accuracy.
Read 1D bar codes as well as 2D codes like Data Matrix
and PDF 417. You can decipher codes applied through
ink jets, thermal transfer, laser etching, or dot peen.
Optical Character
Recognition/Verification
Spatial Calibration
NI OCR functions use a trainable OCR algorithm
specifically designed to identify and verify all types
of fonts, characters, and symbols despite poor and
inconsistent image quality.
Particle Analysis
Use particle analysis to detect connected regions or
groupings of pixels in an image and make selected
measurements of those regions. Choose from more
than 80 unique measurements that return data in
both real-world and pixel values.
Color Inspection
Color matching quantifies which colors and how much
of each color exist in a region of an image and uses
this information to check if another image contains
the same colors in the same ratio.
Edge Detection
Use the edge detection tools to identify and locate
discontinuities in the pixel intensities of an image.
Find edges in order to align, measure, or detect
features in the image.
Object Classification
Classification is a tool for identifying an unknown
object by comparing its significant features to a set
of features that represent known samples.
Using spatial calibration functions, you can calibrate
your image to take accurate, real-world measurements
from images, regardless of camera perspective or
lens distortion.
Image Arithmetic and Logic Functions
Operators perform basic arithmetic and logical
operations on images. Use operators to add, subtract,
multiply, and divide an image with other images
or constants.
Coordinate Systems
Set up coordinate systems to ensure that all your
measurements move with the object within the field
of view.
Image Filters and Frequency Analysis
Frequency filters, such as the fast Fourier transform
(FFT), alter pixel values with respect to the periodicity
and spatial distribution of the variations in light
intensity in the image.
Image Segmentation
NI vision software comes with several options to
segment and partition images into related components.
Segmentation is an important part of many imaging
applications that need to extract certain features or
objects in order to process them further.
Golden Template Comparison
Find defects in an image by comparing a perfect
(golden) sample to all subsequent samples. Golden
template comparison detects surface defects, label
misprints, and overall quality issues.

Configurable Machine Vision Software
Signal Input and Output
Vision Builder AI Development Toolkit
From Vision Builder AI, you can control the industrial digital I/O lines on
the NI Compact Vision System, PCI-8254R, NI PCIe-8255R, and any NIDAQmx data acquisition device to communicate inspection results to
other industrial devices such as PLCs. Beyond simple digital I/O, Vision
Builder AI can also output precise timing signals through pulse
generation and single-shot signals directly to actuators. Moreover, you
can acquire and transmit analog values on any M Series device from
Vision Builder AI in order to integrate data measurements with your
machine vision or generate analog values based on inspection results.
Machine builders, integrators, and advanced users can use the Vision
Builder AI Development Toolkit to develop professional-looking custom
steps that provide functionality not already included in Vision Builder AI.
For example, you can develop a custom step that drives a camera or other
hardware not currently compatible with Vision Builder AI. You also can
create a custom step to include a customized image-processing algorithm.
You can distribute custom steps in addition to the released version
of Vision Builder AI, providing your end users with a customized Vision
Builder AI package.
Industrial Communication
Deploying Inspections
From Vision Builder AI, you can also communicate with devices using
industrial protocols over serial or Ethernet ports and send inspection
data, inspection results, or customized data to PLCs, touch screens, or
industrial PCs.
To deploy your application, use a Vision Builder AI Run-Time license.
The run-time license is a low-cost way to replicate your inspection while
still allowing your operators and engineers to interact with the software
to view images, update parameters, and gather statistics. Each NI Compact
Vision System already comes with a Vision Builder AI Run-Time license.
Benchmark Your Inspections
Use the performance meter to see how fast the application will run. A
detailed view of the performance meter helps you identify time-consuming
individual steps.
Customize Inspections
Vision Builder AI is one of the most flexible menu-based vision software
packages and it includes several features with which end users can expand
and extend the environment to handle most machine vision applications.
• You can use the Run LabVIEW VI step to call any LabVIEW VI from
Vision Builder AI to expand its capabilities. Examples include report
generation tools, custom algorithms, communication routines, or virtually
any other LabVIEW VI. You do not need LabVIEW installed to use this step.
• You can extend the capabilities of your system by converting your
Vision Builder AI script to LabVIEW. Use this code to build a customized
user interface or to add more measurement or automation functionality
such as motion control and data acquisition.
